'Geek speak' - more acceptable

I see today that 'Geek speak' is being criticised. I'm not sure that's fair - why not criticise any other non-familiar register. The definition of a register is: any of the varieties of a language that a speaker uses in a particular social context. Hence 'Geek speak'... and further a Geek isn't necessarily related with the innards of the computing community - a Geek. (In fact there is quite an interesting discussion about what a Geek is here.) You could be a Language Geek, talking of only didactic synchronicities or something.
What I say is - learn the language, look up the meanings of things. Don't complain about your lack of understanding.
